From the few people that have done the IPF it has been shown to give more HP gains than the trifecta. Most of the modded 6s have all agreed that tirfecta is a glorified way of taking off the CEL that comes with headers. Most people have said that there cars are running better without the tune.

when I originally got my Trifecta tune I felt the gains. but after I did more mods I went back to stock for an issue I had, and when I retuned I didn't feel it really. Now as far as how my car runs, it runs great with my tune, I don't feel like ive lost power, and my mileage if I don't use ghost cam isn't negatively affected.

I have yet to be "WOW'd" by any mods performance-wise. (My butt-dyno must be getting fat, old, and cynical...) I must say that the Trifecta transmission tune came the closest though. A close second is the Vararam - not for the performance - but for the change in sound at WOT. I haven't had any issues with the Trifecta tune, my car is running well; but I've read about people feeling that things got better for them after taking it off. I must admit I would like to get an wideband AFR gauge on the car because I've also read about a lean-running issue one member on here had with a Trifecta tune. But that may have been particular to his car/application.

As gustavson said, tran tune is the most noticeable. I have Injen longtube CAI, Ported throttle body when the tune was installed. Have added the ice-olater and need to get a data log back to them to see if it needs adjusting. Mostly I think it is tying all the mods together and making them play nice. Ipf does a great job also.

I wasn't UN Happy with the Trifecta tune...but then againt I can't say I was ever completely satisfied with it either. Now that I'm on the stock tune again and have been months I can honestly say I have no desire to have the tune back. I even sold my cable. Car runs just as crisp and strong as it ever has.

I'm not saying Trifecta absolutely has ZERO gains. Obviously there are dynos out there showing it made power. Stock and modded. There are also dynos (one or two) showing a loss versus stock, and others who say the same as me...feel no difference.

I will go so far as to say... even though there are not as many IPF dynos floating around, they have consistently showed better gains than Trifecta. I'd love to give the IPF tune a go, and I hope to sometime soon (soon means...could be a long time from now lol)...but I have so many other goals, and things I want to do that its putting a tune a bit further down on the list.

I felt no gains from any of mods until after the trifecta. It was like it woke the other mods up. I may be in the minority, but I say it was worth every penny. I even get about 2 mpg more now than stock.

I saw a dyno sheet with a graph of one tuner where it lost HP and TQ down low, but made more HP on the top end. HP = (TQ•RPM)/5252 ? A dyno reads TQ and the math formula converts it to HP. Since Horsepower is TQ times RPM, divided by 5252, the higher the RPM at the same TQ would have higher HP.

I had the Trifecta tune for about a year and I didnt have any problems...I thought it was one of the best mods I did. I took it off 2 days ago and it seems the car runs more "smooth" but I can tell a difference in the gearing for my automatic. IPF, well I wont be able to help you with that opinion since the supercharger is going along with it lol It seems like it is pretty advance though and I havent heard one person complain about the IPF. Trifecta has been slammed and its pretty hard to get in touch, which is one of the downsides.

I have the Hypertech max energy programmer on my car and I can defiantly tell its there. It may not add any more HP but with being able to change shift points, shift firmness, and rev limiter it makes a difference. It feels like I'm getting more response from my car now. The only thing I don't like about its is the lack of being able to turn my speed limiter off. So I just say that my tire height has changed and that gives me 5 extra mph. Haha so instead of 118 it's 123. I've been thinking about maybe trying something else but I'm not real sure what I should go with yet
